Answer:

Lime juice, extracted from fresh limes, is rich in citric acid, vitamin C, antioxidants, and small amounts of minerals such as potassium, calcium, and magnesium. When diluted with warm water and consumed in moderation, lime juice can offer several health benefits, including helping boost immunity thanks to its high vitamin C content, which can protect against colds and sore throats. It also stimulates digestive juices, promotes bowel movements, and may relieve bloating, gas, and constipation.

Citric acid in lime juice supports liver function and helps gently activate the body’s natural detox process when consumed in the morning. Additionally, natural enzymes in lime may assist with weight control by curbing appetite, increasing satiety, and slightly enhancing metabolism. Its antioxidants neutralize free radicals, slowing signs of aging, while vitamin C aids collagen production for healthier skin.

Despite its sour taste, lime juice has an alkalizing effect in the body, helping to balance excess acidity.

However, lime juice can be damaging if misused. Its high acidity can erode tooth enamel and cause sensitivity, especially if consumed regularly without rinsing the mouth afterward. Drinking large amounts or consuming it on an empty stomach may trigger stomach pain, acid reflux, or heartburn, particularly in individuals with a history of gastrointestinal issues.

Undiluted lime juice can also disrupt electrolyte balance and hinder nutrient absorption. Moreover, it may interfere with certain medications, including antibiotics, antidepressants, and blood pressure drugs.

To enjoy lime juice safely, it is recommended using half to one lime per day, diluted in 250–500 ml of water. The best time to drink it is in the morning—after a light snack or about 30 minutes before a meal. Avoid drinking it on an empty stomach or if you have acid reflux, ulcers, or sensitive teeth.
